Abstract

In patients with oral cancer, trismus (maximum interincisal opening [MIO] <35 mm) can develop as a result of surgery and radiotherapy. The aim of this study was to provide an alternative operation to both eradicate oral cancer and prevent postsurgical trismus. In our retrospective cohort study of oral cancer patients who underwent operations during 2010 to 2014, the predictor variable was the type of operation (alternative operation or traditional operation) and the outcome variable was MIO. All of the cases were allocated by 2 periods: the traditional operations were performed from 2010 to 2011, and the alternative operations were performed from 2011 to 2014. All patients received marginal mandibulectomy, anterolateral thigh free flap, and adjuvant radiotherapy or concurrent chemoradiotherapy. In addition to traditional marginal mandibulectomy, the alternative operation included ipsilateral coronoidectomy and myotomy of the temporalis muscle insertion, masseter muscle, and medial pterygoid muscle. MIO was measured at 10 time points. The adjusted variables included demographic data, diagnostic parameters, treatment, and response. Of the 36 male patients with oral cancer, 16 were placed in the alternative operation group (AOG; m...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
